Application filed I une 2, 1908. Serial No. 436,310.

To all whom it may concern Be it known that I, EDWARD H. GUYER, a citizen of the United States, residing at Rock Island, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Combined Type-lVritin and Computing Machines, of which the fol owing is a specification, reference being had therein to the accompanying drawings.

This invention relates to whatA I term a combined typewriting and computing machine, that is a machine which combines the functions of the typewriter and the computing machinejn a manner such that numbers registered and added or subtracted by the computing mechanism, are simultaneously recorded on the paper by the ty ewritin mechanism, the latter being capa le as wel of doing the work of the regular tpewriting machine. AV machine of this c aracter, 1n order to fully meet the widely varied conditions of service should be capable of performing in the usual way to which operators are accustomed, all the functions of standard typewriting machines, of accurately adding or subtracting numbers of great magnitude, and of performing its writing operationsand its computing operations either conjointly or independently at the will 0f the operator. Furthermore, the relations and connections of the recording and registering mechanism should be so flexible that the recording both of registered numbers and of ordinary typewiting can be effected on an part of the paper.

The genera object of this invention is to produce a machine to meet these requirements having a minimum number of operating parts and free from the frail and unreliable construction'that has characterized the machines of this type with which I am familiar.

The manner of attaining this, as well as other more specic objects, will clearly appear in the following particular description in connection with the drawings which illustrate a practical embodiment of the invention.

In designing my machine, I have availed myself of the experience of typewriter Inakers, and it will be observed on referring to the drawings that the typewriting mechanism comprises the structure of one of the standard typewriting machines. Inasmuch as the details of construction of this type- Fig. 6 is a face view of one of the Fig. 16

Writing machine are generally well known, it will be unnecessary for 111(` to refer to them particularly in the description which follows.

Referring in detail to the construction illustrated, 1 is the machine base. WZ and 3 3 are rear and front pillars rising from the base to support the frame -1 of the type- Writing mechanism. 5 5 are pillars rising from the sides of the base 1 to support the framework of a portion of the computing mechanism, all of the pillars referred to consist preferably of tubes and tie bolts as indicated. G designates the type wheel, 7 the printing hammer, 8 the key levers of the typevvriting mechanism, 8@L the spacing lever, 9 the paper carriage, and 10 the ribbon mechanism, all of these parts being essentially of the. Well known standard construction.

T 71.6 dial mechanism-1n this machine the operations of addition and subtraction are effected by means of a series of disk shaped dials arranged side by side and carrying the numerals on their peripheral edges. The supporting frame of the dial mechanism rests upon the pillars 5-5. This frame comprises a base 11 (see Figs. 5 and 30) and upstanding end plates 12 and 13. The upper face of the base 11 is concaved to receive the lower part of the dials 14 and 15 and the dial supporting and spacing disks 16 and 17. (See Figs. 6 and 1Q.) The concaved face of the base is longitudinally grooved or recessed at 11a (see Fig. 30) to receive and rigidly support tubes 18 and core rods 19. Each of the tubes 18 is formed with a series of evenly spaced transverse slots. A series of dial supporting disks 16-17 have their edges entering the tube slots and are accurately centered and rigidly supported by the core rods 19, which engage notches 16-17a formed in the edges of the disks. Each of the disks has a central, circular, aperture surrounded by a bearing collar 16b or 17b to support a dial. The dials 14, like the supporting disks, are formed of sheet metal, each disk having a series of equally spaced notches in its periphery. The teeth formed by these notches are bent laterally and the out-turned face of each displays a numeral, there being ten such teeth numbered 0 to 9, inclusive. Each of the dials is centrally apertured, the periphery of the aperture being notched to form a series of ten inwardly, projecting teeth 14 in radial alinement with the numeral-displaying faces above referred to. These teeth are designed to be engaged by dial-'turning devices later to be described. 14 is a bearing collar or hub 'adapted to fit the outer face of the collar 16b of a supporting disk 16 and to rotate freely thereon.

20 1s a spring carrying-pawl (see Fig. 13) which consists of a half ring of flat spring metal having a centrally arranged outwardly extending projection 20 and in line therewith a laterally extending tooth Q01. This pawl has its ends rigidly secured. as by riveting, to the lateral face of the dial in a position such that the extension 20a is disposed centrally of the notch between the numeral faces 9 and 0.

Just outside of the bearing hub 11a are a series of ten rectangular perforations 11b in radial alinement with the peripheral notches of the dial and in circumferential alinement with the tooth 20h of the carrying pawl.

lvvhen one of the dials is in working position 0n its supporting disk, the tooth 20h of the carrying pawl is in circumferential alinement with an arcuate slot 1GC in the supporting disk. This slot is in radial alinement with what may be termed the reading position of the dials, this position being intermediate the two notches 16 formed in the periphery of the disk and serving .f1 purpose to be referred to later. As the dial rotates with respect to its supporting disk in the direction for addition the tooth 20 of the carrying pawl moves into the slot 1G as the numeral 9 moves from the reading position and numeral 0 comes into reading position, this lateral movement of the pawl being due to the spring action of its arms. In the case of subtraction. with the rotation in the opposite direction, the tooth 20h moves into the slot as the numeral 0 moves out of and numeral 9 moves into the reading position. As the tooth 20b moves into the slot it c-innes into engagement with one of the apertures 11' of the dial of the next higher denomination and carries it forward or backward, as the case may be, one point. As the tooth of the carrying pawl nears the end of the slot 1Gc in the carrying operation, the inwardly extending beveled projection of the tooth 20") engages one of the two beveled faces 1GC and the tooth is thus lifted from the slot. rl`he distance between the beveled surfaces 16@ corresponds to 3G degrees of angular movement of the dial so that a movement of one point for the dial of next higher denomination is thus insured.

It is customary in writing numbers to separate the numerals in groups 'of threes, as a matter of convenience in reading either by the ilse of commas or by spacing. I en1- ploy the latter method. Accordingly the construction of every third dial and its supporting disks is slightly varied. the supporting disks 17 (see Fig. 8) being provided with a bearing collar 17b wider than that of the disks 1G, and the dial 15 being provided with a Correspondingly wide bearing hul) 15. (see Fig. 11).) the width of the hearing collars being such tliat a dial 15 and its supporting disk 17 occupy the space of two sets of dials 14 and supporting disks 1G. Diametrically opposite lugs are formed on the i through the' quill 21 and provided with'a rectangular groove 22a extending throughout its length. This shaft and the surrounding quill are designed to guide and turn av shuttle indicated as an entirety by 23, and I comprising a body part 24 and a collar 25. (See Figs. 14 and 15.) The body part 24 has hooked ends 24aL and a centralnnotch 24b having a width equal to the width of the collar The latter` carries a laterally projecting lug 25a. When the quill, solid shaft and shuttle are assembled as is shown in Fig. 15,y the body part 24 of the shuttle lies in the groove 22 of the shaft,/While the collar 25 surrounds the shaft and body part 24 with the lug 25a extending outwardly through the slot 21 of the quill. The arrangement is such that the collar is free to rotate with respect to the stationary shaft, but can move longitudinally only with the body part 24 of the shuttle, because the collar engages the notch 24b of said body part. lThe lug 25 of the shuttle extends through the slot of. the quill far enough to engage the inwardly extending teeth 14c of the dials, and by suitable rotation of the quill a dial engaged by the lug 25a may be turned any desired number of oints.

The ongitudinal movement of the shuttle to bring it into engagement with the different dials is effected b y means of a steel band 26 (see Figs. 1, 2, 3 and 4)V attached at either end to one of the hooks 24a of the shuttle and adapted to be connected intermediate its ends to' the paper carriage of the machine.

27 is a pulley sup orting frame (see Fig.

5) in the form o a bar' which extends throu hthe base 11 and has its ends bent atrig t angles, as indicated in the drawings to form suitable bearing supports for the spindles 28 and 29, said spindles being .supported preferably on adjustable pivot points.

30 is a sprocket wheel rigidly mounted on the spindle 28 and 31 is a grooved wheel similarly mounted on lthe spindle 29.

32 and 33 are brackets rigidly secured to the end. plates 13 and 12, respectively. (See Figs. 1, 3 and 4.) The free end of the bracket 33 also ,the rearwardly extending arm of the bracket 32-are slotted to receive upright shafts 35 which are adjustably secured in position by means of the bottom nuts 36 and upon which are rotatably mounted grooved pulleys 34, the latter' being secured in place by means of the top nuts 3T.

The pulley frame 27 is so disposed that the peripheries of the sprocket wheel 3U and of the grooved pulley 31 are in line with the path of the shuttle along the groove 22 of shaft 22. The steel band therefore lies in .f

this groove throughout its length and on emerging therefrom at either end passes over the sprocket Wheel 30 and pulley 31. i

The band is perforated throughout its length at regular intervals, the pitch of the perforaf tions being equal to the letter space of the typewriter. These perforations engage the pin-like teeth of the sprocket wheel. From this sprocket wheel, on one hand, and from the grooved pulley 31, on the other, the band passes rearward over the grooved pulleys 34 between which it extends in close proximity to the bar 38 rigidly mounted on the paper carriage of the machine. (See Figs. 1, 3 and 16.) At the middle of this bar is secured a bracket 39 grooved on its lower face to receive a shifting clutch member 40 and I having an up-turned arm in which is rotatably mounted one end of a rock shaft 41, the other end of said shaft being similarly supported at the right end of the carriage where it is provided with `an operating handle 42. At its inner end the rock shaft 41 has a down-turned arm which projects through a slot 39a in the rock shaft bracket to engage the clutch member 40. (See Fig 17.)y This clutch member carries on its front face a plurality of pins 40a properly spaced to engage the perforations ofthe steel band. An angle clip 43 is secured to the bottom face of the bar 38 and is provided with a series of perforations '43a opposite the pins of the clutch. Thus the steel hand lies between the bar 38 and the clip 43 and when the clutch is thrown forward by turning the rock shaft 41, the clutch pins extend through the perforations of the band and into the perforations of the angle clip, thus securely locking the band to the paper carriage. )Vith' the shuttle and carriage thus connected, it is clear that the two will move`in unison, and inasmuch as the distance between adjacent dials is equal to the letter space of the typewriting machine, it is clear that the shuttle will be moyed from yengagement with one dial to engagement with another upon each operation of the escape mechanism of the paper carriage. To secureV with precision the proper position of theshu'ttle with respect togthe dials, the pullev frame 27 is madelongitudinally adjustable.

44 'is a slotted arm carried by this frame adjacent the end plate 13, (see Fig. 2) and 45 is an adjusting screw threaded into the base 11 and having collars to engage said bracket. By turning the screw in one direction or the other the position of the frame, and consequently of the shuttle, can be nicely adjusted. It will be noted that the proper tension for the band is secured by adjusting the position of the pulleys 3l.

'ic 91H7/ operi/tiny /nwcltan/mmhhor the purpose of turning the quill and with it the dials, a series of key levers 16, ten in number, are provided. (bee Figs. 1, 4 and 18.) The keys of thc levers 4G display the numerals l. 2, 3, 4, 5, 6, 7, 8, 9, and O, reading from left to right. These key levers are disposed beneath the frame Ll of the typewriting mechanism, and are pivotally mounted at their rear ends on a hinge rod 17 which extends longitudinally through the slotted bearing block -l-S.

49 is a frame or bail which is also pivotally mounted on the hinge rod 47 and which has its front transverse bar disposed beneath the front ends of the key levers 4G, said bar having its upper edge notched to receive the levers and give them lateral support.

50 is a rock shaft mounted at either end in ball bearings at 50a and having a series of forwardly extending arms 51. (See Figs. 18 and 19.) These arms are preferably in the form of tubes forced through holes in the rock shaft and secured by having their ends expanded. Each arm carries at its outer end a standard having a grooved roller to engage one of the key levers 4G. The standards are adjustably mounted on the arms 51, each carrying a set screw 5i which projects through a slot in the arm 51 to engage an adjusting screw 55, as is clearly indicated in Figs. 20 and 21.

The arms 51 are of different lengths so that an equal depression of different key levels will give to therock shaft different angular movements. Thus the arm 51 engaged by the 9 key lever is designed tol give the rock shaft an angular movement corresponding to a movement of nine points by one of the dials. Similarly the arm 51 that engages the 5 key lever causes the rock shaft to turn a distance corresponding to a movement of ve points by one of the dials. To avoid the necessity of using unduly long rocker arms 51 in the case of the 1 2, and I "i key levers, supplemental levers 57 are providedto coperatc with these key levers. The levers 57 are pivotally mounted at their front ends on standards 5S and are disposed between the olf-set sections of the lever bars 1G and the similarly offset, supplemental bars 46a which are rigidly secured to the key levers. Each of the levers 5T carries at its rear end a transverse pin to engage the lower edges of the lever bar 46 and the supplemental bar 46a. The levers 57 engage the rollers-of the arms 51, and the leverage of the system is such in each case that the desired movement of the rock shaft is secured Without unduly longr arms 51.

'.l`o prevent overthrow of the rock shaft and consequent overthrow ot' the dial to which the motion of the reel; shaft is transmitted. a limit stop is provided in the form of a plate 59 which is rigidly secured to the rock shaft. This plate is formed with a series of fingers 51) corresponding to the kev levers 1 to 9 and each finger carries an adjustable Contact member preferably in the form of a screw 59h in vertical alinement with its corresponding key lever. Yl`he several fingers of the plate 5t) are so disposed in relation to the axis of the rock shaft that upon the depression of any one of the keys the depressed lever and its corresponding contact screw carried by the plate 59 come into contact at the end of the desired movement of the rock shaft and thus positively prevent its further movement.

At its right end the rock shaft carries an armed hub (il to which is rigidly secured the gear segment (i2. (See Figs. 2 and 3.) This segment meshes with an idle gear G3 mounted on ball bearings carried hy the for wardly extending arm lila of the bracket 3Q, see Figs. Q2 and lt also meshes with a` gear (35 rigidly mounted on a spindle G6 which is suitably supported on pivot screws G7 and 68 carried respectively by the bracket arm 32a and the plate 13. At its inner end the spindle G6 carries a second gear 69, which in turn meshes within an idle gear 7() mounted on` ball bearings 71 carried by the end plate 13.

The idle gears G3 and 'TO are concentric with the quill Q1, the latter being carried by a sleeve 72 formed with a ball race constitilting part of the ball bearing 73 in the end of the bracket arm 32, At its other end the quill is carried by a similar sleeve 74 formed with a ball race constituting part of a ball bearing 75 in the end plate 12. The sleeve 72 is formed with diametrically opposite slots 2Q, as shown 'in Fig. Q2, one of which slots engages a spline 21h on the quill Q1, thus locking the two parts against relative rotation.

TG is a movable clutch element (see Figs. and Q5) comprising an outer ring portion 70 having laterally extending beveled teeth 7G". radial arms 76 and a central hub part 76d. Arms T6 are of a width to enter the slots 22a of the quill sleeve and to slide therein. The idle gears G3 and 70 carry ten lateral clutch teeth 63 and TO, respectively, adapted to be engaged by the teeth 76 of the moving clutch element 7G. It is clear that when the clutch 7G is in engagement with thel idle gear 63 that the quill will be turned in one direction by the movement of (see Fig. 22) which supports the right endV of. the stationary shaft 22, the left end of said shaft being rigidly carried by the bracket 79, on the end plate 12. (See Figs. 1, 2- and 4.) The outer end of the spindle 77 passt-.s through a hole in the end of the quill sleeve and is guided thereby. The outwardly projecting end of the spindle is notched at 77C to engage the swinging lever arm 80 which is pivotally mountedA :xt-81 on the upstanding arm 32h of the bracket 32. A weight arm 82 is pivoted to the upper end 'of the lever '.80 with freedom' to 'swing through about 180', the p'ivoted end of theA arm 82 being forked so as to form shoulders' that engage the sides ofthe lever 80 to limit the relative movement of the weight arm and said lever. A weight 83 is threaded upon the arm 82 and may be'locked in anv ,desired position by means of the tubular nut 484. )Vh'en tlie lever 80is in a vertical position the *clutch 76 is in Aan intermediate position and out of engagement with both of the idle gears 63 and 70. The weight arm 82,

however, tends to, move the lev'er 80 to 'he left or tothe right according as said weight arm is to t-he right or the left of its pivotal support on the end 'of lever 80.` Hence the weight'arm tends' to keep the cl'utchcin engagement with oneorlthe other of the idle is guided.) The bail 49 carries at one side gears 63 and 70. l l

'I he lowe'r'end of the'swinging lever 80 Ais forked, as clearly indicated in Fig. 18, so as to form inclined cam surfaces 80a which terminate `at their upper lends in a circular notch, the openingof which is somewhat less than its diameter. 85 is a lever bar pivotally mounted'at its rear end u on an extension of the bearing block 48. ear its front end this lever bar is provided with 'collars" between which is mounted an antifriction roller 86 ladapted toY engage the cams 80a of the lever 80, one or the other of said cams being pressed against the roller 86 by the action ofthe weight arm 82.

87 is an upstanding bracket mounted on the machine base and provided with avertical slot 87a through which the front end of the lever ,bar 85 projects and by whichit a rigid arm 88 upon which is pivoteda depending hook 89 adapted when-the bail is depressed to engage :the end of the lever 85 and to lift thesame as the bail returns to normal position. The hook 89 is provided with asurface 89 adaptedto engage;

lVith the parts thus constructed and alb ranged; it will be seen that when the bail 49' is depressed b v a key lever, the hook 89 is brought into engagement with the front end of lever 85 and as the bail rises the lever 85 is lifted. During this movement of lever 85 it engages one or the other ofv cams 80 of lever 80 so that the latter is swung into an intermediate or vertical position which corresponds to the inoperative position of clutch 76. As the lever reaches this position the roller 86 carried by it'enters the circular notch of lever 8O. .At the same time hook 89 is moved out of engagement with lever 85 and the latter is left in engagement with the circular notch 8O (being prevented from falling from said notch by the lateral pressure -of lever 80 due to weight arm 82) durinf the return of the segmental gear 62 to its normal position. Disengagement of le, vers 80 and 85 is then effected by the following devices: The segment 62 carries a rearwardly extending outturned arm 62sl in Vwhich is mounted an adjustable Contact screw 91, said screw being disposed in vertical alinement with the lever 85. (See Fig. 3.) 92 is a stopjmounted on the machine base in position to engage the arm 62a of the segment when the latter returns to normal position'. Contact screw 91 is designed Vto beso adjusted as to come. into contact with the lever 85, the latter being in its. ,raised'positiom slightly before the arm 62a 'of-the segment engages the stop 92. At its A front end the segment 62 carries a bracket 93 on which is pivotally mounted a locking hook 94. (See Figs. 1, 2 and v3.) 95 is a spring which presses the hook yieldingly against the adjustable screw 938L carried by the bracket 93. 96 is a notched arm'rigid with the lever 80 and projecting through a. guiding slot 32 formed in the lower 'side of the bracket 32, see Figs. 3 and 23. The

Ylocking arm 96A is of such length that its To insurev the prompt return-of the segment and bail to normal position, after tlie depression.` of one of the key levers 46, al ,K weight 97 1s suspended from the bail and the 59, and at the other end to the front cross bar of the bail. A guide pulley 99 is inte"r posed between the weight 'and the bail to secure an upward pull on thc latter.

The key levers 46 are returned to normal position by springs 100. one of which is interposed between each lever land the plate 101, a pin 102 pivotally connected to the lever and passing through a perforation in the plate 101 being preferablyy used to keep the spring in position. (See Figs. 3 and 1S.) This construction is modilied, it will be noted, in the case of the first three ke)7 levers, the springs being carried by the supplemental levers 57, as shown in Fig. 18.

T he (Ze'm dining and locking derivee-To more fully insure the accurate positioning of the dials when turned by the depression ot the key lever, I provide special alining devices, and to prevent movement ot the quill during the ret-urn of the segment. to its normal position, I provide locking devices which engage the quill during such return of the segment.

103 is a tubular rock shaft mounted on the base 1 beneath the key levers 46. (See Figs.- 1, 2 and 19.)l

10ft ale forwardly extending arms carried by this rock shaft in position to be engaged knife edge contacts 105. The latter are preferably carried on threaded Shanks 105 adjustably mounted inthe front cross bar of the bail, thev construction being such that the contact edges may be adjusted forward or rearward with vrespect to the vertical plane of the rock shaft., (See Fig.,4.) On the ends of the rock shaft 103 are mounted rearwardly extending arms 106. At their free ends these arms have upturned sockets to 'receive the lower ends of the upright rods 107.

108 is a transverse bar supported at its ends on the uprights 107, and guided in the straight sided groove 11"' extending longitudinally o .f the base 11, see Figs. 26 and 30. The upper face of this bar is provided with triangular teeth 108a of a thickness adapted to enter the notches or openings between the? numeralv displaying facesof the dials.

When the rock shaft 103 isturned atthe' end of the downward movement o fthe bail, the alining bar 108 is liftedmd the beveled vfaces of the teeth 108 .engage the dials and bring them into accurate alinement.

On the upright 107 at the left of the machine a sleeved locking bolt 109 is slidingly mounted, said bolt being supported by theadjustable nuts 110. The upper end of this bolt is forked to embrace the end of the alining bar 108 and carries a notched plate 109 with a laterally projecting pin 109".

111 is a locking wheel rigidly mounted on the quill sleeve 74, see Figs. 14 and 22,

` its lower end for adjustable connection with a supporting socket 116, the latter being carried on the arm 117 which extends laterally from the side bar of the bail 49. A lock nut 11S serves to secure the upright rod 115 in adjusted position, which is such that when the bail is in its normal position, the upper end of rod 115 presses against the lower side of lever 112 to hold the locking bolt 109 in engagement with one of the pins of the locking wheel.

119 is a depending hook pivotally secured l90 by means of the screw 119a and spacing sleeve 119b to the end plate 12, and having its notch or hook proper disposed adjacent the front lQwer corner of the lever armv112. The lower end of this hook is provided with a beveled or inclined edge which cooperates with the inturned end of the horizontal arm 120earried-by the upright rod 115. .The relation of the parts is such that the arm 120 normally holds the hook'out of engagement with the lever arm '112, but'permits it to swinginto en gement therewith upon the first part of. tie downward movement of the bail.

The clz'al releasing dogs-Viththe dialsv and carrying pawls constructed as'previously described, it is necessary to' provide `some means to prevent thev live dial, that is,A the one engagedby the shuttle, from carrying with it one or more of the dials of lower denomination, this action being possible if theA adjacent.` di'al of lower denomination happens to be in position with its carrying pawl in the slot 16c of the interposed supporting disk.

A rock shaft 121, formed with a rectangu- 'lar groove throughoutits length, is mounted directly above the dials with bearing supports in the end plates 12/and .13. 122 is a pawl or dog having at itsfree end engaging vteeth 122, and at its other end formed with `a boss or sleeve to sli'dinglyengage the rock shaft 121. (See Figs. 2 7 and 28.) The teeth 12.2a are fiat4 at their rightv` sides and beveled on their leftsides and normally lie in the notches 16d of the dial carrying disks 16. These notches 16d lie adjacent the ends of the arcuate slot 16 of each disk so as to, laterally expose the extension 90a of the adjacent carrying pawl 20, when the latter is hooked ond 123 to receive one end of a perforated steel band 124-. 12.5 is a loose hook member adapted to receive the other end of' said steel band and secured to the dog 122 by means of the flanged 'collar 126 which is threaded upon the sleeve of the dog. The steel band 124 lies within the rectangular groove of the shaft 121 throughout the length thereof, passing at the right over a sprocket wheel 127 mounted on the upright spindle 28, thence transverselyA of the machine to the grooved pulley 128 carried by the spindle 29. In assembling the parts the desired tension of the steel band is obtained by adjustment of the threaded collar 126.

The dog 122 is normally pressed downward by spring 129, so as to bring its engaging teeth 122a in line with the notches 16d of the pawl carrying disks 16. The spring 129 is mounted upon the fork t130, the latter being rotatably secured upon the sleeve of the dog between the face of the dog arm and a detachable securing nut or collar 1221. The fork is prevented from turning by reason of its engagement with the collar of the overthrow detents which presently will be described.

It is clear that the sprocket wheel 127 will move the steel band 124 and'with it the dog 122 in unison with the paper carriage and the shuttle 23. The parts are assembled so that the dog 122 is always just one space to the right of the dial engaging lug 25a of the shuttle 23. Consequently as the shuttle moves into engagement with the dial next to be turned, the dog 122 moves into position above the adjacent dial of next lower denomination and one or the other of its teeth l122a at the same time engages the pawl .extension 20a of the last-mentioned dial in case it is in positionfto bring said exten sion in line with either of the notches 16c of the dial supporting disk. By this engagement the dog withdraws the tooth 20b of the pawl from engagement with the live dial; that is rto say, the dial next to be turned. Before the dog 122 can move 'another step to the right, it must be lifted to disengage it from the pawl projection 20ik and to this end I provide the following mechanism.

The left end of the rock shaft 121 projects through the end plate 12 to receive an arm 131 which normally rests upon the spacing sleeve 119b of the depending hook 119. 132 is a lifting pawl having its free end notched at 132al to engage the end of the rocker arm 131. This pawl is pivotally connected at its lower end to the arm 133 bail.

of the rock Shaft 134, the 4latter being piv- V otally mounted in the tubular shaft 103.

See Fig. 26. The latter shaft is partially cut away inits middle part to permit the connection of an arm 135 with the inner shaft 134. 'libe arm 135 carries en extension 135awh1ch projects into the path of the space bar 8a of the machine. The space bar in turn carries an extension 8b which projects into the path of the bail,V so that the space bar is depressed by the latter part of the downward movement of the bail, the carriage escape mechanism operatingat the very end of such movement. (See Figs. 3 and 26.) lith this construction, the shaft 134 is rocked both by the depression of the space bar and by the depression of the The rocker arm 133 carries an adjustable stop screw 136 to limit the down- (See Fig. 4.) Near its upper' end-the lifting pawl is bent to form a cam surface 132b which cooperates with a rigid pin 79a projecting from the face of the plate 12.`

137 is a spring for maintaining cam 132b in yielding contact with the pin 79". This' spring is carried by a collar 138 which is adjustably secured to the bracket 79 by a screw By loosening the screw the col.- lar may be turned to properly position the spring and then be secured rigidly in position by tightening the screw. The rela tion. of the parts is such that the cam 132b forces the pawl out of engagement with the arm 131 after a slight upward .movement of the latter. This upward movement of the arm 131 causes a similar lifting of the dog 122 and this is timed to occur an instant before the escape-mechanism of the paper carriage operates to permit the movement o'f said carriage. It is clear therefore that the momentary lifting of the dog releases the carrying pawl which may have been engaged by one of the dog teeth and permits the dog to move in unison with the paperV carriage one space to the right, engaging in such movement the pawl extension 'of the dial over which it moves'incase such extension chances to be in the path of either of the dog teeth.

Since the dog 122 is maintained one space to the right of the dial engaging lug of the shuttle, and is consequently always found directly over the dial of next lower denomination than the live dial, it Serves as a pointer to indicate the live dial. When the pointer is moved to the left'by the return movement of the carriage, the dog rises automatically over the pawl projections I20a that maybe in its path by reason of the beveled conformation of the left faces of the dog teeth 122. l

The overthrow detents.-Overthrow of carried by the segment rock shaft, which has been described above. But it is also desirable to provide means to prevent the overthrow of the carried dial. To this end I provide the two detent segments 140,

which are pivotally carried on a sleeve 141. j(See Figs. 29 and 30.) This sleeve is car- -ried by a frame comprising a transverse rod 142 upon which the Sleeve is slidingly mounted, and upright end plates or bars 10 143 which are notched attheir lower ends to engage the aliner bar 108. The end plates are slotted at 143a to embrace the quill and at 143b to receive the rock shaft 121. Mounted in this manner the frame is guided for vertical movement in unison with the aliner bar 108, when the latteris forced upward by the depression of one of the computing keys in the manner previously lde scribed.

The segments themselves are slotted to permit the passage through them of the rock shaft 121 and at their lower ends are formed with three dial engagingteeth 140". l/Vith the dial in a normal position of rest,

the middle one of the three teeth 140a projects into the space between two of the numeral displaying faces of the dial in position to be engaged as the dial is turned. Such engagement causes the oscillation ot the segment, thus causing one or the other of the two outer teeth 140a to pass into the next adjacent notch in 'the-dial. The movement of the dial is thus arrested, inasmuch as the oscillation of the segment is limited by engagement with the rock shaft 121.

The segment carrying sleeve is moved longitudinally of the rod 142 in unison with theA dog 122 by the fork 130 carried by said dog, the fork engaging a suitable groove in 40 the detent sleeve. This connection between the dog 122 and the sleeve of the overthrow detents is such that the detents are always maintained in position to engage the two dials of next higher denomination than the livedial. Two of the detent segments are necessary on account of the grouping of the dials with intermediate spaces, for`a single segment would be inoperative when it fell in one of these intermediate spaces. With two segments, the engagement of one of them with the dial of the next denomination is always insured. Of course the use of a second detent segment might be avoided by f making the width of the numeral displaying faces of the dials 15 equal to the Width of the bearing hubs 15".

It will be understood that as the support` ing frame of the detent segments is carried upon the aliner bar, said segments will be 60 lifted with said aliner bar an instant before of them that has been previously rotated is restored to a vertical position by means of the rock shaft 121 bearing against the side of the triangular shaped opening in the segment, so that the center tooth of the segment is in position to engage the notch of the next dial of lower denomination.

The type leser connections-*In order that the numerals registered by the dials by the depression of the computing key levers 46 may be printed on the paper simultaneously with such key depressions, I provide means for connectingl the computing key levers with the numeral key levers of the typewriting mechanism proper, the 30 latter being in the uppermost row of the bank.

144 is a transverse bar rigidly mounted` on the typewriter frame directly above the upper row of key levers. (See Figs. 31, 32 g5 and 33.) This har is provided with a series of vertical holes one above each' of the key levers of the upper row in which holes are slidingly mounted plungers 145, each having its lower end resting upon the upper edge of the key lever beneath. An upstanding connecting link 146 is pivotally secured to each of the computing key levers 46, and each of these links is formed at its upper end with a rearwardly turned flange 146. 95 Each of these flanges carries an adjustable contact screw 147 adapted to engage one of the plungers 145. Each of the flanges is also perforated to receive one of a series of upstanding guide pins 148 which are carried upon a sliding plate 149. This plate is provided with slots through which the plungers 145 project and the plate is free to move forward and' back a distance corresponding to the length of these slots. This movement is effected by a longitudinally sliding shifting rod 150 mounted in brackets 151 and connected by means ot links 152 with a sliding plate 140. The shifting rod is provided at its left end with a handle 150a by 110 which the rod may he moved. This handle is formed with two locking notches 150b adapted to be engaged by a locking detent 153 to secure the plate 149 in either of its extreme positions. When said plate is drawn back, the contact screws 147 are in vertical alinement with the plungers 145, so that the depression of the computing key levers 46 causes the depression of the corresponding numeral key levers in the upper row. When the plate 149 is thrown forward said screws are out of alinement with the plungers and the levers in the upper row consequently are not effected by the depression vof the computing levers. A
